Huntington Beach will partially close the intersection of Indianapolis Avenue and Brookhurst Street to strengthen the ground in the area, according to officials.

A city crew was doing routine maintenance on a sewer line when they noticed a broken pipe with material inside. It was later determined that air pockets had developed under the pavement, which could potentially compromise the integrity of the road, according to press release.

The city closed two northbound and southbound lanes on Brookhurst and will close additional lanes as construction begins, Public Works construction manager Eric Charlonne said. He added that the date to begin the improvements has not yet been set.

Charlonne said that the city will have to repair the sewer line and reconstruct the area by a method that has yet to be determined.

"It could be anything from an excavation with an injection of some concrete slurry in the area or excavating down to below where the voids are apparent and physically get down to those locations and filling those up with concrete," he said.

Officials said it could take up to four weeks to complete the project.
